Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed May 16, 1914. Serial No. 839,046.

To all whom it may concern Be it known that 1, CLAIR L. VAN N'nss, acitizen of the United States, and residing at Akron, in the county ofSummit and State ofOhio, have invented certain new and usefullmproven'icnts in Insulating-Heads, of which the following is aspecification.

I This invention. relates to certain new and useful improvements ininsulating heads, and is an. in'iprovement upon the type of ill-- in myPatent #1,l00,002, June 16, 191 the present invention, like the one justreferred to, being preferably, though not necessarily, of the multipleform/ The presentinvention has for its main object to provide means in'an insulating head, for adjusting the wire guider or guiders so as tocompensate for the side pressure within the insulating chamber againstthe wire being insulated, and thereby absolutely having a detachablepoint or nipple, where-- by different sized nipples may be used with thesame guidcr-spindle, obviating the ne- 5 cessity of changing guiders fordifferent sized wires, and effecting a considerable saving in cost. 1

Other objects of the invention will appear as the same is hereinaftermore fully described and claimed, and in describing the' invention indetail, reference will be had .to the accompanying drawings illustratingpreferable embodiments of my invention, it being understood thatalthough herein illustrated as a multiple formol insulating head,

I do not limit or confine myself to such construction or arrangement, asthe forms of guider and die shown may be used singly in an insulatinghead.

In the drawings: Figure 1, is a longitudinal sectional view of aninsulating head showing a preferred form of guidcr anddic construction,the relief valve of the insulating' head being partly broken away, Fig.2, 5b is a view of the same form oi insulating head, the view beingpartly in elevation,

sulating head shown, described, and claimed partly broken away, andpartly in longitudinal section, Fig. 3, 'is a horizontal fragmentaryview of part-oi an insulating head, illustrating a modified form of wireguider 6g and mounting therefor, Fig. 4, is a similar view showing thedie which is used with the lorm ol' guider shown in Fig. 3, and Fig. 5,is an end view of the guider shown in Fig. 3, the insulating head beingbroken away. 5

Insulating heads of the type here "shown are known generally as sidedelivery type, that is, a type in whichthe material with which the wireis coated is fed to the side of the wire instead of in line with thewire, the latter type of devices being gener-v ally known as straightdelivery devices. The insulating head lere shown, like in my patentreferred to, isadapted to be attached to a suitable compressor fromwhich the material is fed into the insulating head. As the constructionof the insulating head per se, and the relief valve therefor are fullyshown and described in my patent, they will be referred to and describedonly generally herein,

i The insulating head, like in my patent, is shown as consisting of amain member 10,

' and. a cap-plate 11,the two members forming an insulating chamber 12,for which a relief valve 14, (fully shown. and described in my priorapplication) is provided.

As stated,'thc present invention relates particularly to the wireguider, and the manner in which the same may be adjusted.

As shown in Figs. 1 and .3, the construction embodies a mounting inwhich both the wire guider and the die are received, such mountingcomprising a gu'ider-sleeve 15, and a dieslceve 16, mounted respectivelyin the main member 10, and cap plate 11, and connected together bytie-bars 17, spacedequidislant, and having their inner edges rounded offso as not to interfere with the passage of the plastic material onto thewire.

p The guider-slecve is provided at its inner end with a seat 18 and atits outer end has a head 19 which abuts against the outer face of themain member 10, and has a rounded or convex outer face forming anexternal seat 20. This guider-sleeve 15 has its bore 21 tapering, beingwidest at the outer end oi" the sleeve, and through this tapering boreis received the hollow-spindle 22 of the wireguider. The said spindle ofthe guider is formed at its inner end with a head 23 rounded for seatingengagement with the seat 18 and having 'a threaded socket for thereception of the threaded shank 24 of the guider-point or nipple Thehead and nipple 25 are each preferably provided with fiat surfaces 26,or their equivalent, in

order to enable implement.

Outside the guider-sleeve 15, the guiderspindle carries a pillow-block27, which has a concave inner face 28 that seats upon the convex outerface 20 of the sleeve head 19,

gripping by a wrench or like being held in any position thereon to whichit may have been adjusted by lock-nuts 29.

The mounting or connector for the guider and the die is locked at theother end by a. lock-nut 30, threaded onto the outer end of thedie-sleeve 16, said sleeve being also interiorly threaded to receive thedie 31.

In the construction shown in Figs. 3, 4t,"

same reference numerals have been used on all those parts which areidentical with the construction of Figs. 1 and 2.

3 The die 31 in this construction is mounted in a die-sleeve 16'threaded into the capplate 11, and for This pur ose provided at itsouter end with a head 1 In order that the sleeves 1-5 and 16' may bethreaded into the members 10 and 11 respectively, the peripheriesthereof will be fiat-faced as shown for the head 28 of the-sleeve 15,

that they may be readily gripped by a wrench. j I j I In Figs. 1 and 2,the three upper guiders are shown in difierent adjusted positions, theone at the left being shown with the guider ,point or nipple perfectlyalined with the die, the one inthe center shown slightly adjusted so asto'somewhat off-set the nipple point with respect tothe die, and the oneat the right hand side of the figure shown adjustedto the full limitpermitted.

The adjustment of the guider is efi'ected by a slackening of the nuts 29and then delivering a side blow mpon theplllow block 27. The guider itis-to. be observed 15 clamped between two curved seats that have aspherical movement on a. common-center. Whena blow is delivered on-theplllow-block -27, it reverses the nipple point, 'slnce the seat centeris within the limits of the length of. the guider member.

By this simple and effective adjustment it will be noted that I amenabled to readily and quickly adjust the wire guider nipple withrespect to the die, so as to compensate for the side pressure within thechamber 12 against the wire being insulated, as with a rigidly heldguider, it has been found that the pressure of material against the wirewill throw it out on a curve through the die,.

- causing eccentric insulating of the wire,

which 1s, by thls construction, wholly eliminated, simply by moving theguider point or nipple over at an opposing angle to the'side pressuredelivered.

In practice, any one or more of the openings may be blanked as shown inmy prior application, or a filler block may be inserted in the chamber12 as shown by dotted line 32, Fig. 1, the inactive guiders being ofcourse removed.

What I claim is:

1. An insulating head comprising a wire die and a wire guider, theopposed terminals of which are disposed in parallelism,

the two members in fixed relation to each other whereby to displace bothends of the first member.

3. An insulating head comprising a wire die, and a wire guider bodilyand swingingly adjustable relative to the die whereby to displace bothends of the guider.
